Once, a man who believed in fairy tales married a beautiful, mysterious woman named Indigo Maxwell-Casteñada. In exchange for her love, Indigo extracted a promise: that her bridegroom would never pry into her past.

But when the couple return to Indigo’s childhood home, they find the shadow of another girl lurking in the manor’s extravagant rooms: Indigo’s beloved friend, who disappeared without a trace.

Faced with his wife’s dark secrets, the bridegroom is unable to resist breaking his promise. Even if it threatens to destroy their marriage . . . or their lives.
